thecoolmankyle Posted April 25, 2020 Share Posted April 25, 2020 (edited) Ok I've been chasing this sound for a couple weeks and im looking for some input, hoping others have had the issue. 05 LGT wagon. 5MT Did the cobb adjustable STS install. Now I have this crazy rattle in acceleration coming from the shifter. Ive taken it out several times and check the o rings around the bottom, re-greased it, and checked the bolt and tightened it. I'm starting to lean toward changing the original white bushing at the bottom and new O rings, thinking maybe its not seating right with the new shifter. Any thoughts or experiences would be appreciated. Did a search and seams like other people had rattles coming from heat shields and crap. This is directly related to the shifter. You can grab it and it quits, you can move it slightly forward and it quits or lift up on it. Its worse in 2nd and 4th. EDIT: Yes I did trim the metal plate back for clearance.

Max Capacity Posted April 25, 2020 Share Posted April 25, 2020 FWIW, you can drive the car without those heat shields. 90% of mine have been removed for many years. I have not rattles that might can from them. That big one over the drive shaft was the first to be removed back about 2011. 305,600miles 5/2012 ej257 short block, 8/2011 installed VF52 turbo, @20.8psi, 280whp, 300ftlbs. (SOLD).

Yea I have already had 2 rattles I had to chase down because of them, they are probably going soon! I wish this was a heat shield they are easy to deal with.

rhino6303 Posted April 25, 2020 Share Posted April 25, 2020 The fork to shifter is most likely too tight and/or the shifter is adjusted too short. I would start by raising the shifter to the suggested setting and loosening the shift fork. It only needs like 5 ft. lbs. of torque. That's barely over finger tight.

I know I way over tightened it then! I'll report back! Link to comment Share on other sites More sharing options...
MaasaiWarrior Posted April 25, 2020 Share Posted April 25, 2020 My old Cobb sts buzzed all the damn time, no matter what I did new bushings, lubed everything up I even installed a brand new shifter basket. This was in 3-5 on a 5 spd. I sold it and went back to stock. The noise instantly went away and driving is so much more peaceful 08 Spec B, insta: @08_spec_b, 10 SH Forester insta: @shfozzy Link to comment Share on other sites More sharing options...
thecoolmankyle Posted April 26, 2020 Author Share Posted April 26, 2020 Well I loosened up the shifter fork bolt and it seams to have went away. I’ll know more tomorrow when I drive it more but if it doesn’t stop then I’m going back stock too. Sent from my iPhone using Tapatalk Link to comment Share on other sites More sharing options...
Infosecdad Posted April 26, 2020 Share Posted April 26, 2020 If you can't get it to quiet down, I'm quite happy with a Kartboy SS. Link to comment Share on other sites More sharing options...
SubOperator Posted May 4, 2020 Share Posted May 4, 2020 I have a 6MT Cobb STS for my STI 6MT swap and it rattles a lot of times. Comes from the reverse lockout ring, if I hold it then it is quiet. I don't know if it due to the fact that it is hollow but from what I hear it is Cobb STS's "feature". 2005 LGT Wagon Limited 6 MT RBP Stage 2 - 249K 2007 B9 Tribeca Limited DGM - 272K SOLD - 2005 OB Limited 5 MT Silver - 245K SOLD - 2010 OB 6 MT Silver - 205K Link to comment Share on other sites More sharing options...

wpmarky Posted May 4, 2020 Share Posted May 4, 2020 That happened to me too with the 6mt cobb sts. I had to twist the reverse lockout cable around the shifter to tighten it up. It was too loose after I shortened the throw and was rattle around inside. Went away after a couple twists. Good luck -Mark I have a 6MT Cobb STS for my STI 6MT swap and it rattles a lot of times.

I will try to undo the handle and give it couple of twists, may be that will put enough tension on the ring without making it too difficult to operate.
